5 Matching Questions

  1. chitin
  2. condensation reaction
  3. hydrolysis
  4. nucleic acid
  5. polymer
  1. a A polymer (polynucleotide) consisting of many nucleotide monomers; serves as a blueprint for proteins and, through the actions of proteins, for all cellular activities. The two types are DNA and RNA
  2. b A chemical process that lyses, or splits, molecules by the addition of water; an essential process in digestion
  3. c A structural polysaccharide of an amino sugar found in many fungi and in the exoskeletons of all arthropods
  4. d A long molecule consisting of many similar or identical monomers linked together
  5. e A reaction in which two molecules become covalently bonded to each other through the loss of a small molecule, usually water; also called dehydration reaction

5 Multiple Choice Questions

  1. A storage polysaccharide in plants consisting entirely of glucose
  2. A discrete unit of hereditary information consisting of a specific nucleotide sequence in DNA (or RNA, in some viruses)
  3. A type of nucleic acid consisting of nucleotide monomers with a ribose sugar and the nitrogenous bases adenine (A), cytosine (C), guanine (G), and uracil (U); usually single-stranded; functions in protein synthesis and as the genome of some viruses
  4. A chemical reaction in which two molecules covalently bond to each other with the removal of a water molecule
  5. The form of native DNA, referring to its two adjacent polynucleotide strands wound into a spiral shape

  2. carbohydrateone of two types of nitrogenous bases found in nucleotides, characterized by a six-membered ring. Cytosine (C), thymine (T), and uracil (U)

          

  3. polypeptideA long molecule consisting of many similar or identical monomers linked together

          

  4. lipidOne of a family of compounds, including fats, phospholipids, and steroids, that are insoluble in water

          

  5. monosaccharideThe simplest carbohydrate, active alone or serving as a monomer for disaccharides and polysaccharides. Also known as simple sugars, the molecular formulas of monosaccharides are generally some multiple of CH20
